Casodex

How does it work?

This medicine contains the active ingredient bicalutamide, which is a type of medicine known as an anti-androgen. It works by blocking the effects of male hormones such as testosterone (androgens). Prostate cancers are sensitive to testosterone, and their growth is increased in the presence of this hormone. This is because testosterone binds to androgen receptors on the prostate cancer cells, and causes changes within the cells that result in faster growth of the cancer. Bicalutamide works by preventing testosterone from binding to the androgen receptors on the prostate cancer cells. It therefore starves prostate cancer cells of testosterone, which prevents them growing. Eventually the prostate tumour will shrink. Bicalutamide is used in two doses. Bicalutamide 150mg is used to treat locally advanced prostate cancer, either by itself, or in addition to treatment with either radiotherapy or surgery to remove the prostate gland. Bicalutamide 150mg is also used to treat locally advanced prostate cancer in people for whom surgical castration or other medical treatments are not appropriate or acceptable, provided the cancer has not spread to other parts of the body. Bicalutamide 50mg is only used to treat advanced prostate cancer, and only in combination with either surgical castration, or a different type of anti-cancer medicine known as a "gonadorelin analogue". This class of medicines can cause a short-term worsening of symptoms before the improvement begins, and bicalutamide can prevent this.
